As soon asthe valve 1l closes air pressure on the opposite sides of the firing pin9 are equalized by Vmeans Vof holes in the Walls of the pistol above thering pin as indic-atedV at 23 and the firing spring is, therefore, freeto drive theiiring pin downwardly Without pressure interference. The Yair pressure is utilized tol cool; the pistol and compress the firingspring, this air pressure being subsequently neutralized at the momentof tiring by the Closing of valve l1. This neutralization of thepressures,v of course, permits this iring spring 16 to eX- pandinstantly withl sutHcient force to ignite the cap engaged by the firingpin V9 carried by the valvey 10.

Vll/Thile the operation has been described with Lrelation to itssuccessive Vsteps and terms have been used which might-imply a slownessof operation for the saire of clearness, it is, of course, to beunderstood that the complete operation ofthe entire device is almostinstantaneous. Y

From the above it will be seen t-hat the presentyinvention provides asimplerland practical-pistol having relatively feivrparts which may beinexpensively manufactured and assembled and the simplicity of design isVespecially to be noted in connection Wit-h its Ysafeness andreliability. Y

Without further analysis, the foregoing will so fully'reveal the Ygistof this invention that others can by ,applying current knowledge readilyadapt it for various applications Without omitting certainfeatures that,from the standpoint of the prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this inf vention,and, therefore, such adaptations should and are intended toibeeomprehended within the meaning and range of equivalency of thefollowing claims.

That- I claim is:` Y Y l, In a device of the character described, incombination, a. valve carrying member, a plurality of valves and valveseats asso- Ciated therewith, one of said. valves beingV subjected topressure 1 in the Vcombustion flask to close a second valve, said secondvalve being associatedwiththe third valve t-o open. the same as saidsecond valve approaches closed position,.said-device being Yprovidedwith means for equalizingV the pressure on fthe oppositefsides -ofsaidfirst mentioned valve and aktiring spring asso- Leiated therewithadapted to move theirst lmentioned valve to firing position Vafter thesaid firing spring istcompressed on movement of said iirstrmentionedvalve whereby when ysaid second mentioned Vvalve is Closed the pressureon the opposite sides of said rst mentioned valve becomes equalized andf permitsrsaidl tiring spring to operate.

3. In a device of the character described, in combination,V a valvecarrying member, a second valve adapted togbe closed on movementof saidmember and a relief valve adapted to be openedV during the closing ofsaid second mentioned valve.V

a 4f. In a 'device of the character described,` 1n combination, a mainvalve, a firing pinV associated therewith, said valve having a passagewhereby pressure may beequalized upon opposite-sides of 'said valve, asecondary valve, a eompressionispring actingbe-VV tween the adjacentsurfaces of said valves, and a. normally closed spring actuated relief\f'alve,'vvhereby a relative movement of the main valveV causes aclosing of the sec-V ond valve and an opening ofthe relief valve thuspermitting equalization of pressure on opposite sides of the mainvalveto restore said first mentioned valve to its 4former posi- 1 tion thusbringingthefring pin into opera#Y tion.
